Use of the MMPI to predict effective hotline workers.

The present study investigated the use of the MMPI to discriminate between two groups of hotline volunteers: those who after training would become effective interviewers and those who would not. Effective interviewers were defined as those who emitted 40% or more good responses when they were responding to a crisis call. The criterion measure employed was the Therapist Error Checklist. When a specification equation based on standard MMPI scales was used, 91% of effective interviewers and 90% of ineffective interviewers were identified correctly.
